Khloe Kardashian knew Tristan Thompson was the one 'quickly'

Khloe Kardashian has confessed she knew Tristan Thompson was the one "very quickly" because she felt "comfortable and safe" with him straight away.

The 'Keeping Up With The Kardashians' star - who is expecting her first child with the basketball star - says she had an instant connection with her partner when they first met and she felt "comfortable and safe" with him straight away.

Writing on her app, she shared: "My answer for this probably doesn't apply to everybody, but I knew Tristan was the one very quickly - I have never felt so comfortable or so safe with someone. Because of that, I took it very slowly and was cautious about how I went about 'us'. I made sure we had very in-depth conversations. I wanted to make sure that those conversations were backed up by actions.

"Tristan was so forthcoming with his life, as I was with mine. It was really reassuring to feel that someone had the same belief systems as I did. We spoke about religion, children and our families. I think all of those things are important to truly know the ins and outs of someone. It's really easy to fall in love with someone during a honeymoon phase when you haven't yet discussed the logistics of life. But you have to talk about the real things if you want a real/long-lasting relationship."

Meanwhile, Khloe previously admitted her pregnancy is "physically and mentally trying" but praised Tristan for making everything "as easy and beautiful as it can be".

She said: "Having a partner that is equally as excited as you are, and is such a support system, is crucial! Tristan has been an angel to me! This process is trying - physically and mentally - but Tristan has made everything as easy and beautiful as it can be! More than I could have imagined."
